Joker uses everyone, it's a core part of his personality.

hmmm i think in the beginning the joker just had around for her to fill up his ego and make him laugh...but some how she got in and he doesn't like it...since he is insane it's like a switch, every time there is remotely any evidence of him having a slight molecule of love for her he wants to kill her...and as crazy as that's sounds...you know you love someone when you WANT to kill em :P

he likes her slightly but mostly he uses her

No the relationship is totally one sided he uses her for her skills and loyalty he would kill her in a second. She is a big joke to him the way she loves him so much in everything he does but he does not and just uses her hurts her humiliates her. That is just another joke in his mind. The Joker is so sick and twisted and evil he feels no sexual or romantic feelings. He is extremely vain and loves himself always putting himself above anything his ego would not let him fall in love as well 

he would kill her..but he hasn't...lalala

" i think shes used "

"In Last Laugh when he thought he was dying he wanted Harley to have his child, and on many other occasions he has randomly killed everyone working for him. So in some way he does love her since he hasn't killed her yet, but because he is insane and incredibly egotistical he sees her as expendable."

He killed her in Emperor Joker. Though he did it because he cared about her and not just for the sake of killing.  "

You know, I downloaded the demo for Batman: Arkham Asylum the other day and read Harley's bio that is included with the game.  It describes Harleen Quinzel as the Joker's "greatest victim" in the sense that he has actually done more harm to her and through her than he ever could with anyone else. 
 
"You always hurt the ones you love."

There is no way in HELL he loves her. I feel bad for Harley really.

Ditto. "

It is already stated that the Joker is super-sane. He recreates his persona everyday, to fit the occasion. Some days, he might just really care for her (not love her, I have never seen him do that before), the other days, she's just one more person who he didn't kill yet. 
 
Frankly, I think it will take a long time before the two get in the love boat again. Joker is more bad ass then ever right now, and I don't think he'll be in the mood to care for her again. 

She's used and manipulated to his benefit.

With the amount of times hes thrown her out windows illd say he uses her unless thats his way of saying i love u

He doesn't love Harley in the sense that normal people love someone. He loves her in his own sick and twisted way. He has tried to kill her many times. And, although it has already been said, he won't kill her. He likes that she has an infatuation with him and he uses that to get to her. Does he love her is not the correct question its more of does he care for her. And the answer to both of them is yes. In his own way yes he does.

She was used and abused.

He uses her..He never cared for her..

He goes back and forth. Deep down he does have a twisted affection for her but his personality changes every twenty seconds. He definitely uses her but part of him genuinely cares -- and it scares him.

Nah, she's a total tool.

I personally believe it's both. She is used because her complete purpose for him is really to do what he says, and she does it probably the best out of all of his gang because she is infatuated and will do anything he wants. He could tell her to jump off a bridge, and she'll jump off the bridge, in a sense. But if he told a random member of his gang to jump off a bridge, that person will not jump off the bridge..Harley will probably push him off the bridge for not doing what the Joker told him to do. But I think that some times that without Harley he would really be lost some times and he has grown accustomed to having her around. I think the deepest affection he has is "What would I do without Harley? I'm too lazy to do it myself."

he uses her badly he treats her like crap but what i cant understand is even though i was shocked and angered by the fact that he would do this i still like him hes like charlie sheen

She's being used. I say the only woman Joker has ever truly loved was Jeannie Kerr (Joker's pregnant wife before his face got bleached).

BOTH
He cant love, not fully.. he is a psycopath.
But he cares for her in the only way he can

To answer the question directly NO I don't think he does. He uses her in countless situations and often times you can tell he thinks she is very expendable and doesn't think much of her.

You make it sounds like Psychopaths can't love.

That's because they can't. But the Joker might not be a psychopath.

Ive always seen the Joker as sociopath incapable of true love, the ''love'' he shows to Harley is solely for selfish reasons..

I always thought that he enjoyed her deep devoution to him, which gave him a sort of self approvel, but in the end she was just an emotional tool for him. Harley and Joker are two different sorts of sociopaths the one with no ability to show true love, the other shows love similair to a child: Accepting, intense, sometimes... selfish and finally, just like a child she will be extremely loyal. Where the Joker only does the things he do for personal gain and uses her love as a tool but still needs her for his own selfish satisfaction and acceptance.

So in than sense.... he uses her but their relationship could he studied for ages, its actually brilliant. Its proberly the most perfect thing the animated series gave life to.

Use her.

I'd say the joker doesn't see her As a Partner. He just sees her as another minion but if he has to fake some things to keep her, he will.

He does love her, he just doesn't like to admit it!!!

I doubt he would have put up with her if her if he didn't!

Joker doesn't love her. He's shot her at point blank range, launched her in a rocket and numerous other things, and very often puts Batman top on his list of priorities above her. Joker finds her amusing and sometimes even fun. She's a very convenient tool and plaything when she's going all gaga for Mistah J.

IMO he doesn't love her. For me he uses her with a bit of obsession thrown in because he considers her a work of his.

If any of you have read Arkham Asylum The psychologist there claims that the Joker has super sanity, which is why he seems to be a silly clown some times, and a murderous psycho other times. His personality is constantly changing, this makes the most sense for me as to why the joker acts so differently during different story arcs while they all take place in the same continuity. It also explains why he treats Harley differently all the time, being affectionate some times, and torturous others.

used.

In way maybe the Joker does love Harley but not in a way that we would understand. He probably loves her like how a dragon loves it's gold.

I believe the Joker in his own sick way loves Harley. If he really didn't he would have killed her, he did attempt it when he pushed her out that window but he must have felt like he had to apologize because he left her a flower with a little note, for someone who dosn't care about humanity that says alot. Also he skinned a man alive for looking at her, he has in the past tried to kill her out of jealousy.

Obviously, the Joker is not one for loving emotions, although it would be safe to say that their relationship is bizarre enough that he often does treat her fondly, in a weird, violent-romantic, way.

Here is a little Wikki Proof-

Harley's relationship with the Joker is one of the most complex in the DC Universe. While he often abuses her, sometimes near the point of death, there are as many instances that show a mutually affectionate side to their bizarre relationship. Certain stories imply that the Joker wrestles with the confusing reality of actually caring for someone, giving in to the sentiment more or less at times depending on his mood or state of mind.

In the book Batman: Animated, Mark Hamill (who provided the voice of the Joker in Batman: the Animated Series) says "Expressing emotion in any way that's real and meaningful is alien to the Joker, but he's learning those parts of himself, however unconsciously, through Harley."

Sorkin adds, "Everyone else sees the Joker laugh; Only Harley has ever seen him cry."

One example of this affectionate bend in their rollercoaster relationship comes from the Emperor Joker series (Action Comics #770) where Joker shares with Harley his deeply personal reasons for destroying the universe. Instead of destroying her with it, he gives her a last kiss and turns her into a constellation, saying "You get the best seat in the house for Armageddon. Say goodnight, Harley. I always wanted to see my dame in lights. Heh. Even in a moment of abject saccharine, I still got it."

A more in-depth look at the early stages of their DC Universe relationship is provided in Greg Rucka's No Man's Land novel. In the book Joker's initial reaction to Harley in her new mental state is a mixture of fascination and annoyance. Something that he can only seem to guess at causes him to not kill her and to keep her around, and as they spend more time together he begins to enjoy her more in spite of himself. One part describes Joker observing Harley during one of their outings, "Harley, he had discovered, had tricks. One of her favorites involved a rusty cheese grater and a stapler. It didn't always work, mostly because people didn't tend to sit still for that sort of thing, but it gave Joker a consistent laugh, and he figured in time Harley would have it down to a science."

Another part describes Joker choking Harley in frustration, and then a quick thought or two later grabbing her, kissing and licking her, and saying to her excitedly "Harley. You are the greatest, you know that?"

In Batman #663, it is revealed that Harley included in her college thesis the theory that the Joker is constantly reinventing his personality; After she is corrupted, however, she refuses to accept that his love for her is not a constant. Furthermore, Joker relents after Harley defends herself against him, saying he will let her live, but that it would be better if she were disfigured. She apparently consents, but Batman attacks as Joker traces a razor against her cheek. The issue ends with Harley putting a bullet through Joker's shoulder.

I think he loves her the way one loves a good seat on the bus.

Loves her because he left flowers on her desk? It was only to manipulate her back to him.

I don't think he loves her. Not in the slightest and not even in his own way. Ofc he is attached to her because it's convinient to have a henchgirl who adores her and does anything Joker wants. But he easily replaces her in the comic and in TAS also...

The only person the Joker loves is Batman.

@peppeyhare: So true. Except himself of course.

It's an abusive relationship; plain and simple.

I think he love's her, and that's exactly why he wont get close. After Jeannie, he does not want to get close and lose it all again!

@hattermari: I thought that was just a random flashback that may or may not have been true?

I think Harley just fulfills Joker's ego, he has somebody to admire his work which he doesn't often get. Harley loves him but that's merely a fantasy for herself because he'll never love and that's not his nature as opposed to Batman which he can.

When you compare Harley Quinn's relationship with Joker with Catwoman's relationship with Batman, it obvious why its so twisted. The Joker spins Harley into a immature girl overdosed with love, whose he's constantly pushing into more darker and terrible situations. Batman on the other hand with Selina, doesn't change her, he provides with opportunities to do good or to at least help her out on the occasions when she could. However they both let each other be even if they don't always agree with it as opposed to Harley who is willing to get almost killed or arrested just for the Joker and the opportunity of love.

The Joker broke Harley, why Batman made Catwoman stronger. Hence why the world of Batman always have interesting relationships.
